We do not rank students in our school, and our school is really competitive.
I am thinking about premed/computer science/ business, which schools are in my reach and would also give me a pretty good finicial aid?
(I heard Emory is really good for Pre-med, but its CS sucks, but I might go there if I chose pre-med, what is my chance on that?)
